TTC #2 for over a year

Hi guys, I’m just looking fir some advice. I’ve been TTC for over 1 year, I’ve got a 7 year old daughter (my current Fiancée not her father) I have just had my coil out last November! So this ya Xmas #2 with no pregnancy, I’m getting very down about it now. I’ve been to docs and they’ve checked my blood to make sure I’m ovulating and they say I am! Me n my partners lifestyle hasn’t been the healthiest (we eat well mostly) so we now back at gym and changing our diets, stopping smoking. (I’m hoping this will make a difference)

I was hoping to get some advice on foods, drinks, supplements for both of us to try out and try get things moving! Xxx
